We’re not big fans of tubular carbon fiber tent stakes, because hikers tend to use them inappropriately in soils that are too rocky or hard. However, the experienced hiker knows that there are specific use cases that make them valuable: soft and medium-density soils where the large diameter provides good holding power. We like the ZPacks Carbon Fiber Stake the best, because its metal head and sharpened tip make it easy to insert into more dense soils.
